Keeler Portable Slit Lamp (PSL): A Versatile and Portable Solution for Ophthalmic Examinations
The Keeler Portable Slit Lamp (PSL) is an AC-powered biomicroscope designed to facilitate the examination of both the anterior and posterior segments of the human eye. This device allows for detailed visualization of frontal and posterior structures, including the eyelid, sclera, conjunctiva, iris, natural lens, and cornea. With its advanced features and portability, the PSL is an ideal solution for ophthalmic examinations, particularly useful for elderly, disabled, or young patients.
Versatility and Portability
The PSL combines the ease of use of a desktop slit lamp with portability, making it extremely practical. It is perfect for situations where a conventional slit lamp cannot be used. The portability of the PSL makes it an essential tool for clinicians on the move or in various clinical environments.
High-Quality Optics
The PSL offers exceptional optical quality thanks to its multi-layer, multi-element glass optical system. This ensures optimal clarity and maximum performance, allowing for precise and detailed diagnosis of ocular conditions.
Robust and Lightweight Construction
Constructed with a precisely machined aluminum chassis, the PSL is both lightweight and durable. Its ability to withstand the rigorous conditions of daily ophthalmic environments makes it a reliable choice for healthcare professionals.
Variable Illumination
The PSL features continuously variable illumination, adjustable from zero to maximum. This functionality allows for the adjustment of light intensity according to the specific needs of each examination, ensuring optimal visualization of ocular structures.
Accessories and Mounting
The device comes equipped with LED mounting targets, activated by a double-click on the trigger, and a 1 mm square aperture for evaluating uveitis. These features facilitate a comprehensive and accurate examination of the eye.
Slit System and Filter
The PSL uses a rotating slit wheel system, offering a slit length of 12 mm and an angle of +/- 60º. Filter options include red-free, blue, neutral density (0.8), and clear, enabling versatile examinations suited to various clinical needs.
Binocular Biomicroscope
The PSL is a portable binocular biomicroscope with converging optics at 13º. It provides two levels of magnification: fixed 10x for the PSL One model, and 10x and 16x with lever change for the PSL Classic model. The working distance of the objective is 100 mm for 10x magnification and 80 mm for 16x, with a field of view of 16 mm and 10.5 mm, respectively.
Dioptric Adjustment and Weight
The ocular dioptric adjustment is +/- 7 diopters, allowing for personalized adaptation for each user. The portable unit weighs approximately 900 g and measures 238 x 116 x 210 mm, while the charging station weighs 300 g and measures 205 x 138 x 40 mm.
Power Supply
The PSL is powered by a switchable power unit, compatible with voltages from 110V to 240V. The output is 30 VA (12V DC 2.5A), ensuring stable and reliable power.
